You do have to wonder, though, if Garak participated in some way in the events on Bajor. He often made up stories that involved activity on Bajor, such as the stories about 'Elim' that he told Bashir in "The Wire", or when the record keeper in the episode "Cardassians" said she was in the underground, and he said, "Then perhaps we have met!", but that could just have been Garak trying to play mind games with whoever he was addressing. After all, you could never really trust what he was saying.

But, I agree that he was probably rather indifferent to the events on Bajor. He never seemed particularly troubled by it, and I don't recall him ever really bringing it up.
